Great information here .
I am tempted to buy a Swytch, but I do like the option of professional fitting provided by Zehus.
New Swytch is a lot easier to install. They now have Brompton specific fittings
Hey did you test the steel or the titanium versîon?
I would like to know the Model of brompton is it for this set. 6 gears or 3?
Nice video. I like the minimalist design of this kit. Also the fact that there isn't a battery back that can potentially hinder using a bag on the frame clip. The only limitation I see is on the speed limit and regenerative breaking for me. As you know, I've been rolling with my Switch kit. One thing I learned that's not advertised, is the kits specs adjustment capability. I was able to optimize my kit at 20 mph (US limit) and adjust the detection and sensor read timing of the magnetic sensor. I am curious of how much optimization the Driiven will allow.
CosFlow Effect hey! Swytch allows me to adjust acceleration and max speed in two separate settings. This allows me to have a slow acceleration and max top speed. The Zehus rolls this into one setting. So you can only have slow acceleration and low max speed or fast acceleration and high max speed. It does have cadence level detection. But it's only useful in low power assist level where there is a range of acceleration. At the max power assist, even pedaling slow will just launch you. The zehus max speed cut off is what e-riders call going off a cliff. The sudden motor cut and rolling resistance feels like someone hit the brakes. Swytch doesn't have this problem because you can set the cut speed to the max level the motor can support you. Swytch requires adjusting the PAS (pressing buttons) to meet the same affect of cadence detection. Have you tried reducing the current down to 7A? It gives a more natural acceleration and longer ride.
@@DrJamesT I have not tried lowering the current, but I did reduce the PAS level amount. Default is 1-9. I switched it to 1-5. I feel like this gives me better range of control on how much assist I want. I've also adjusted the time the motor kicks in as per acceleration. It still kind of jolts forward, but gives me a longer period of slow movement before kicks in. Will the Driiven allow for speed beyond 15mph? How's the battery life and consumption on various speeds?

Have Zehus improved the motor since you made this video?
Great video DrJames. Can you share your opinion on how difficult it is to ride with the motor off? Also would it be difficult to repair a rear puncture?
There is a hack that lets you repair a tire without removing the wheel. Removing the motor wheel is the same as a normal wheel. This motor has no wires. Check out @3:14 for motor resistance test, while I was riding on down tower bridge. Riding flats is like riding up tower bridge.
Please make a video on how to register the zehus to the app. Im having trouble getting the 2 connected
It's via bluetooth, same process as pairing with a bluetooth headphone. If you can't get it to work, it sounds like a call to tech support is required.
My Brompton has a dynamo lighting which attach to rear tire. I don't know if I the new rim can still attach my dynamo kit there too?
I don't recommend friction based dynamo kits for this system because you are using electricity to turn your lights on via friction, which is wasted as heat. Rechargable led lights is direct electricity to light.
hi Dr James, wonderful video.
question: i am keen on this setup and it seems timely that i get another brompton for this, especially for my wife. it would suffice to get a single speed bro for this yeah? is it worth it to get a s1e-x (titanium version)? and plonk the zehus bike+ on it? i mean is the steel version heavy?
you should do a hummingbirdbike review soon!
ascensionyze X yes to single speed version because you’ll be replacing the wheel and hub. Driiven has its own titanium triangle so you just need to buy a steel brompton, titanium fork, titanium Driiven.
DrJames I have the 2009 titanium w/ all the bells and whistles. Including the light. And 6 speeds. Will I loose all these features if I add the Zehus ? How to order this in USA ? Who will know how to install it? Is this the best option? Is the new Switch a better option?
It looks like a good kit... but it's ludicrously expensive! I fitted a kit (not Swytch) to my Brompton B75 and got an electric B for about £1300. It might not be as technologically advanced as that kit but it was easy to install (about an hour for me) and does not compromise the fold in any way. I get about 35 miles range on level 3 (out of 5). A lot of kits are way out of most peoples budget.
which kit did you buy?
Thoughts on the pricing and design? It costs less than the official e brompton. It's lighter. I'm sure the BIKE+ will be better.
Can you tell me what color is that brompton ? Looks like grey but not original color is it ?
That brompton is so cool
John Kang custom powder coat glossy grey done by a specialist in hackney london cost £300
Good video DrJames. I've a question. Can I use the rear wheel gear with this product installed?
Yes you can
Are you saying I can use 2nd, 3rd or 6th gear on the rear wheel?
Which zehus pair up should I review first: Hummingbird or Moulton or Vello+
1st of all, great video! Yours is probably the only one that puts a practical test over this misterious electric kit.
To answer your question - I'd love to see your review on Vello+. Personally I ride Vello Urbano v1.0 basically everyday and I love it! I rode once Vello+ while I was living in london (bikefix has it) and I was amazed.
Comparing any bike+ to Gocycle would be even more awesome!
So is Zehus the best option for adding Brompton ekit? Or is there better option out there? Thanks.
@@NewWorldDAO It's the most expensive option. Swytch is the budget option to consider. Check Nano (UK) and Grin Tech (Americas) has been around for 10 years.
Years ago, I bought original BROMPTON with us in slovenia. I can not find a kit komplet for him.
I think that with the last drive on electricity, I would save you this with a kit and how much would cost mi.
Sordini Orlando this kit is for the rich folks. Keep using your legs your heart will thank you
DrJames _ He might be Rich, How much?
I’m guessing that the disadvantage of this sleek design (battery+motor combined) means that you can never fly with your Brompton if if you frequently travel with it by air?
Each carrier limits by number of Amp Hours of the battery. So I wouldn't use the word never you just need to find the carrier that accepts it
Great video. May i ask you what was your total cost of this special Brompton bike with E Engine ?????Sorry i havent found it. And is there a possibility to buy it in Austria? With best regards Alex
Used Brompton £500 + £300 new paint job and tune up + £1200 for motor and titanium triangle at the time of review. Check the website for latest prices. These come from Italy so it might be cheaper for you EU folks.
@@DrJamesT thanks for your information......Top job
How easy / what cost is it to replace the battery it seems to be built into the frame?
the battery is inside the motor hub itself - you have to send it back to get it replaced.
@@DrJamesT Wow! that seems like a very interesting design - thanks for the response.
Can I ask how this is better than the aarc conversion kit? Seems less user friendly
It looks better. Your brompton bike won't have a battery on the frame. It's lighter.
Does it need a Smartphone to function?
It does not. But you'll need to tweak it. It works with both iphone and android. You can get an android phone for £20-£40
Hello, i have this motor and i have a huge problem registering this beast
Try using another phone or call Zehus
While these look nice, it's a terrible idea to have everything in the wheel. Hard to change parts of something goes wrong. Lots of weight in the wheel. But mainly all the heat from the motor and controller will damage the battery.
....this means - no shiftier and when a battery is drain out you have only one gear to continue your ride ! Maybe in 3 years you have to change your battery and because of this super design , how much it will cost you?? :)
A 2 speed shift from the factory 6 speed version is possible. The Bike+ version can be charged by cycling it -> crazy workout. I agree in 3-5 years time the mileage might decrease to impractical levels. The company apparently will service it at a cost. It should cost no more than a third of the motor price. This is why the zehus kit is recommended for the rich folks. It's the best in terms of design but like a super car, the price is for people with a practical mindset. If you want a budget kit get the Swytch kit. If you want something in between or beyond check out the Grin Tech series. If you live in the UK and have the cycle to work scheme at your company go for the official brompton.
NO WAY would I want to use my phone to control an electric bike. What if the phone had run out of electric?
Peter Simonson you set it once and that’s all you need. The rest is to monitor the motor. The electric bike itself can run out electricity. Risks is the same. Bring a spare power bank.
Battery inside a hub is a bad design, its added weights and centripetal force to the wheel. There is more drag when you pedal and Its will also ruin your bearing.
solid points
Too big a motor and too much of a modification to the original Brompton. I prefer a smaller motor in the front wheel and leave the rear wheel unchanged.
OK all these, but back up is crap and too complicated
what do you mean by back up?
Zehus, unfortunately, has the poorest most unhelpful customer service. Their claims of designing a product to stop thieves are a lie. They would not help me find my bike when stolen and withhold information about the location of my own property for no reason.
